Subcontractor Compliance Software: A Buyer's Guide for UK Contractors

You've got 30 subcontractors, each with employers' liability insurance, public liability, CSCS cards, CIS verification, and trade certificates. That's roughly 240 documents, each with its own expiry date. When one lapses, you may not find out until an HSE inspector asks for it.

General contractor management tools handle scheduling, progress tracking, and payments. Compliance software solves a different problem: are your subcontractors legally allowed to work on your site right now?

This guide explains what subcontractor compliance software does, how to evaluate it for UK construction, and when a dedicated tool makes more sense than a compliance module bolted onto a broader platform. For a wider look at the subcontractor management software category, see our buying guide.

The compliance document lifecycle

Compliance isn't a one-off check. Documents cycle through five stages, and your software needs to handle all of them:

1. Collect — Insurance certificates, CSCS card details, CIS verification, trade qualifications, RAMS. The bottleneck is chasing subcontractors. Software that lets subs upload directly from their phone (photograph a cert, submit in 60 seconds) removes this friction.

2. Verify — Is the EL certificate current? Does the cover amount meet your £5M minimum? Is the CSCS card type correct for the work scope? Manual verification is slow and error-prone. Good compliance software flags mismatches automatically.

3. Track — Every document has an expiry date. EL and PL certificates typically renew annually. CSCS cards expire every 5 years. CIS verification status can change between tax years. The software needs to maintain a live register with countdown tracking.

4. Alert — Automated reminders at 30, 14, and 7 days before expiry. Not just to you — to the subcontractor as well. By the time you notice an expired certificate manually, the gap may have existed for weeks.

5. Report — When a Tier 1 client auditor arrives or HSE inspects, you need a clean compliance pack within minutes, not hours. The software should generate audit-ready reports showing current status, document history, and any resolved gaps.

Most general contractor management tools handle step 1 (document storage) and stop there. Dedicated compliance software covers the full lifecycle.

UK-specific requirements your software must handle

Software built for the US market or designed as a generic international platform will miss requirements that are specific to UK construction:

CDM 2015 compliance. The Construction (Design and Management) Regulations 2015 place specific duties on principal contractors. You must verify subcontractor competence (Regulation 8), maintain construction phase plans, and keep records of inductions and RAMS. Your compliance software should link competence evidence to specific operatives and projects — not just store files in a folder. For a full breakdown, see our CDM compliance guide.

Employers' liability insurance. A statutory requirement under the Employers' Liability (Compulsory Insurance) Act 1969. Your software must track policy numbers, cover amounts, insurer names, and expiry dates for every subcontractor — and distinguish EL from PL and PI cover. Our free insurance expiry calculator shows what this tracking should look like in practice.

CIS verification. The Construction Industry Scheme requires you to verify each subcontractor with HMRC and apply the correct deduction rate. Verification status can change, so your software needs to flag re-verification deadlines — not just record the initial check.

CSCS card tracking. Individual-level, not company-level. A subcontractor with 15 operatives has 15 different cards with different types, numbers, and expiry dates. The software should track each operative separately.

Building Safety Act 2022. The Building Safety Act 2022 is raising competence requirements across the industry. If your compliance software can't track competence evidence beyond basic certifications — training records, CPD, role-specific qualifications — it may not keep pace with tightening requirements.

Dedicated compliance tool vs. compliance module

The market splits into two categories:

Dedicated compliance platforms focus entirely on document collection, expiry tracking, and audit reporting. They tend to be simpler, cheaper, and faster to implement. If your primary pain is "I can't tell which subcontractors are compliant right now," this is what you need.

Broader contractor management platforms include compliance as one module among many — alongside scheduling, payments, safety management, and project tracking. They're typically more expensive and take longer to set up. If you need all of those features, the integration is valuable. If you only need compliance, you're paying for capabilities you won't use.

How to decide:

• Managing 10–30 subcontractors with compliance as the primary gap? Dedicated tool.
• Managing 50+ subcontractors with compliance, scheduling, and payment needs? Broader platform may justify the cost.
• Currently using spreadsheets for compliance? A dedicated tool is the lowest-friction step up. A full platform change is a bigger commitment.

What to test before you commit

Before choosing any compliance software, run this practical evaluation:

• Upload test: Ask a subcontractor to submit an insurance certificate using their phone. Time it. If it takes more than 2 minutes or requires a desktop, adoption will be low.
• Expiry alert test: Set a test expiry date for next week. Does the system send reminders at the intervals you configured? Do reminders go to both you and the subcontractor?
• Audit report test: Generate a compliance report for all subcontractors on a project. Does it show current status, document history, and outstanding gaps in a format you could hand to a client auditor?
• UK compliance test: Can the system distinguish between EL, PL, and PI insurance? Does it track CSCS cards at individual level? Can it record CIS verification status?

If a tool fails any of these tests, it's not solving your actual problem — regardless of how polished the dashboard looks.

Use our free compliance checklist generator to map out exactly which documents you need to track for your trade types and project scope. That gives you a concrete feature list to test against.
